Product Introduction

Two pressurised side plenums form the core of this double-sided air shower. Their opposed nozzle arrays provide cleaning air from both sides of the operator while screened lower returns collect the released particles. The layout is designed for facilities that require fuller all-around garment coverage than a one-wall air shower but retain a one-person entrance route.

Key Features

Opposed nozzle fields reduce shadow areas on the side of the body away from a single air source.

Individually aimable outlets support adjustment for different garment lengths.

Two return paths collect air from both sides of the passage.

Removable inner access panels simplify cleaning of the nozzle and return surfaces.

Straight-through door alignment gives operators an intuitive direction of travel.

Customer Product Concerns

Two active walls must improve body coverage while keeping airflow distribution and service access manageable.

One-sided airflow leaves protected surfaces on the far side of the operator.Matched arrays on the two sidewalls deliver air from opposing directions in the same cycle.

One side may feel stronger when the plenums are not balanced.Separate fan branches and balancing adjustments can equalise the two nozzle banks.

Crossing air streams may keep particles in the central passage.Paired low-level returns remove the contaminated air along both walls.

Internal maintenance disrupts the occupied passage.Serviceable nozzle panels provide access without dismantling the outer enclosure.

Typical Applications
